Hello list,

just in case somebody finds this googling, here is my preliminary 
finding. I have deleted the program description in phpMyAdmin and that 
fixed the problem for this time.

The problems with tv_grab_eu_epgdata and UTF-8 (or whatever) encodings 
are re-occuring but seem to be random. All other program descriptions in 
the last days are encoded correctly, just this one did not come in 
right. In other occasions, I had all program titles and descriptions 
wrong, now it is just some programs.

For the myth programmers, it might be interesting to find out how a 
program description can interrupt the comunication between frontend and 
backend. I can supply a backup of my recorded table (off-list), if 
required. I am not able to analyze that myself.

Thanks for all the support, regards,

Matthias
